Very immature

Unfortunately, the band is sometimes very inaccurate. Many "small" activities, it recognizes no steps. Bin eg home recorded repeatedly from room to room, about 90 min. And what does this part? That's right, nothing.

Then I can just take the iPhone when it eh only works when going out. Since I got my phone eh there ...

From the app never mind ... Although is now better, but still full of errors.
Works Health Sync with iOS 8, almost not at all. It reads data from there, but writes only some and not always ...

So one can not do anything.

Therefore: Currently rather not buy.

PS: the second star's only because the comfort is good and the part looks good.
